Talk to a Specialist →Start With the Distinction That Trips Up Most Buyers
Federal law — the Housing for Older Persons Act (HOPA) — governs who a community is allowed to restrict, not who a community must accommodate. HOPA requires that at least 80% of a community's occupied homes have at least one resident age 55 or older. That leaves a 20% allowance for households that don't meet the age requirement. But here is the part that surprises people: the 20% allowance is not an entitlement. Federal law doesn't force any individual community to let your adult child move in. It only sets the ceiling on how much flexibility a community is legally allowed to have. Whether a specific community actually uses that flexibility — and how — is decided entirely by that community's own governing documents (its CC&Rs, bylaws, and board policy), not by HOPA itself.
That single distinction — HOPA sets a ceiling, the HOA decides the floor — is why you'll hear completely different answers from different communities to the exact same question.
In 2026, an HOA in the Arbor Mill 55+ community near Jacksonville, Florida sued to remove a 28-year-old woman who had legally inherited her father's home there after his death. Her attorney's framing of the dispute captures the whole issue: ownership and occupancy are legally separate. She could keep the deed. Whether she could live in the house was a completely different question, governed by the community's own age-restriction documents — not by the fact that she owned it outright. The case was still working through the courts as of this writing, but the lesson for buyers doesn't depend on the outcome: never assume that owning a home in a 55+ community, whether by purchase, gift, or inheritance, automatically comes with the right for a person under 55 to occupy it.

The Three Real Pathways for an Adult Child to Live There
When people ask "can my kid move in to take care of me," they're usually describing one of three legally distinct situations. Which one applies changes the answer completely.
Ordinary occupancy under the community's own rules
Some communities simply allow adult household members of any age to live with a qualifying 55+ resident, full stop — no special caregiver designation required, because the household still counts toward the 80% threshold (only one resident per unit needs to be 55+). If the community's governing documents don't specifically prohibit non-spouse adult occupants, this is usually the simplest path. It's also the one that varies the most: some communities have never restricted this at all; others cap total household size or require the additional occupant to be a specific type of relative.
A documented live-in caregiver provision
Many communities maintain a specific caregiver policy, separate from ordinary occupancy rules, that lets a live-in caregiver reside in the home regardless of the caregiver's age — as long as the caregiving relationship is genuine and documented. This usually requires an application to the HOA board, a doctor's letter or care plan establishing medical necessity, and sometimes periodic renewal. An adult child providing genuine care can typically use this pathway, but it's a formal process, not an assumption — showing up with your belongings without going through it is exactly how disputes like the Jacksonville case start.
A Fair Housing Act "reasonable accommodation" for a disability
This is a distinct legal right, separate from HOPA's 20% allowance entirely — and it's the one buyers are least likely to know about. Under the Fair Housing Act, a community must make reasonable accommodations for a resident's documented disability, which can include allowing a live-in aide or family caregiver under 55 even if the community is otherwise at full 55+ occupancy. This isn't automatic: it requires a specific accommodation request, medical documentation connecting the request to the disability, and the community can push back if the request would impose a genuine undue burden or fundamentally change how the community operates. This is a fair-housing legal process, not an HOA courtesy — if you anticipate needing this pathway, involve an attorney or a fair-housing agency early rather than negotiating it informally with the board.
What to Actually Ask Before You Buy
If there's any realistic chance an adult child will need to move in down the road — and for most families buying into a 55+ community in their 60s or 70s, there is — get specific, written answers before closing, not after you need them.
- Does the community have a written live-in caregiver policy, separate from its general occupancy rules? Ask to see it, not just hear about it.
- What documentation does the HOA require to approve a live-in caregiver — a doctor's note, a formal care plan, periodic re-certification?
- Is there a cap on non-55+ occupants the community is already approaching? A community near its 20% ceiling has less flexibility left than one well under it.
- What happens to occupancy rights if the 55+ resident later moves to assisted living or memory care but keeps ownership of the home?
- What happens on inheritance — can an heir under 55 occupy the home, rent it, or must they sell? This is exactly the dispute at the center of the Arbor Mill case.
- Get every answer in writing from the HOA or its management company. A verbal assurance from a sales agent or a neighbor is not the same as a documented board policy, and it will not hold up if the board changes its mind or its membership later.
Common Questions
Does it matter whether my adult child is providing hands-on care versus just living with me for company or cost-sharing?
Often, yes. Communities that have a formal live-in caregiver exception are usually looking for evidence of an actual caregiving relationship — not just any adult relative moving in. If the real situation is "my adult child wants to live with me" rather than "I need documented care," pathway 1 (ordinary occupancy rules) is more likely to apply than the caregiver-specific provision, and whether it's allowed depends entirely on that community's general occupancy rules.
Can the HOA change its mind after approving a caregiver arrangement?
Governing documents and board policies can change over time, and an arrangement approved under one board isn't automatically guaranteed to survive a policy change under a future board — though most communities honor existing approvals. Ask specifically whether an approved caregiver arrangement is tied to the individual resident (i.e., protected for as long as they live there) or to a renewable policy that could be revisited.
Is this the same as a HOPA "80/20" question, or a fair housing disability question?
They can overlap, but they're legally distinct. The 80/20 allowance is about HOPA's age-restriction exemption and how much flexibility a community is permitted to build into its own rules. A fair housing "reasonable accommodation" is a disability-rights request that can apply even in a community with no remaining 20% flexibility left. If your situation involves a diagnosed disability, the reasonable-accommodation pathway may be available even where the ordinary occupancy answer is no — this is worth a conversation with an attorney familiar with fair housing law, not just the HOA board.
Does state law change any of this?
The federal HOPA framework and Fair Housing Act apply nationwide, but state and local landlord-tenant law, probate law, and some state civil rights statutes can add their own wrinkles — particularly around inheritance and eviction procedure, as the Jacksonville case illustrates. Treat anything state-specific as a question for a local real estate attorney, not a general guide like this one.
This page explains how these rules generally work and is not legal advice. Every community's governing documents are different, and disputes like the one described above show real financial and legal consequences for getting this wrong. If a live-in caregiver arrangement is a realistic possibility for your situation, get the specific community's written policy and, if needed, a consultation with a real estate or fair-housing attorney before you buy.
